Created attachment 174011 [details] failure info We update the CentOS-7.0-1406-x86_64-DVD kernel to kernel-ml-3.19.2-1.el7.elrepo.x86_64,then we reboot system and enter 3.19.2 kernel. The screen stop at boot message as attachment shows. But you can log in use ssh, and "uname -a" show the system has been updated with new kernel. Why the screen printing stopped and show failure boot with new kernel?
